使用触发器更新SQL表

Question

我正在用列表

[ID] [bigint] IDENTITY(1,1) NOT NULL,
[CompanyID] [bigint] NULL,
[EmployeeName] [nvarchar](50) NULL,
[EmployeeGSM] [nvarchar](50) NULL,
[EmployeeNumberOfDaysOfAnnualLeaveInEachMonth] [decimal](5, 2) NULL,
[EmployeeTotalNumberOfAnnualLeave] [decimal](7, 2) NOT NULL

每月1日00:00:00我需要使用触发器更新EmployeeNumberOfDaysOfAnnualLeaveInEachMonth值的EmployeeTotalNumberOfAnnualLeave增量列

问候

Answer 1

假设SQL应为UPDATE Table SET EmployeeTotalNumberOfAnnualLeave = EmployeeTotalNumberOfAnnualLeave + EmployeeNumberOfDaysOfAnnualLeaveInEachMonth

你可以：

1）创建一个存储过程来执行任务：

CREATE PROCEDURE UpdateEmployeeTotalNumberOfAnnualLeave
AS
BEGIN
    UPDATE Table 
    SET EmployeeTotalNumberOfAnnualLeave = EmployeeTotalNumberOfAnnualLeave + EmployeeNumberOfDaysOfAnnualLeaveInEachMonth
END

2）创建预定作业：

  

1）展开Sql Server Agent

     

2）右键单击作业 - ＆gt;新工作

     

3）给它起个名字

     

4）转到步骤 - ＆gt;新 - ＆gt;将其设置为执行您的程序

     

5）时间表 - ＆gt;新 - ＆gt;将其设置为在每个月的第一天执行

     

6）启用作业
